Looks like the original SCTE. Novak 6.5 motor, maybe a castle ESC?
It would be very funny and cool if that was my uncle's old SCTE which he got rid of several years ago. I was comparing the servos, savox servo just different part number, he actually had a Hobbywing/ tekin motor in his. Hobbywing V2.1 / XR10 Pro. He had a Novak 4.5 turn motor in that thing. It was fast down that 100 ft straight. (indoor carpet track)
